CONDENSED-WATER TRAP.

SPECIFICATION forming part'of Letters Patent No. 421,559, dated February 18, 1890. i

Application iiled August 23, 1889. Serial No. 321,695. (No model.)

To @ZZ whom it may concern.:

Be it known that I, ISAAC CUMBERBATCH,"

of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Condensed-Vater Traps, of which the following is a speciiication.

My improvement relates to traps in which waters of condensation from a steam system are received. g

I will describe in detail my improvement, and then point out the novel features in claims.

The accompanying drawing is a vertical section of a trap embodying my improvement.

A designates a oase or shell. In thecase or shell is arranged a diaphragm A', which divides the same internally into two chambers A2 A3. In the upper of theseY chambers is arranged a ball-float A4. This ball-oat is arranged upon a spindle A5, which spindle in this example of myimprovement is hollow and extends diametrically through the float and is secured thereto upon opposite sides. The spindle is open at both ends.

B designates a valve. This valve is arranged in the chamber A2, and is adapted to be seated upon the valve-seat B formed in a central opening a in the diaphragm A. TheI valve B is mounted upon a valve-stem B2. This valve-stem, as here shown, is hollow. The bottom of the chamber A3 is provided about centrally with an opening b, in which is iran ged an upwardly-extending tube or pipe ed and engages a screwthread upon the tube or pipe B3.

Upon the valve-stem B2 is a'circumferential enlargement B4, which extends normally into the pipe ortube B2. This portion B4 constitutes a plug the diameter of which is such that when within the pipe or tube B3 it nearly closes the same, leaving but a thin Vannular space between it and the inner wall of the pipe or tube.

At some distance below the plug-like pora tion B4 there are formed openings ,c in the wall of the valve-stem B2, which openings communicate with the interior of the valve-stem and also with the interior of the pipe or tube B5. The spindle A5 of the iioat entends downwardly into'the pipe or tube B3 and normally The opening b is internally screwthread past the openings c. The diameter lof the spindle A5 is such that it nearly closes the inner ends of the openings c, and it is also such that only a thin annular space is left between it and the inner Wall of the valve-stem B2. The lower extremity of the valve-stem B2 is secured to an expansion-chamber, as shown, by ineansof a'screw C', which eXpan sion-chamber is one of a number arranged within a case or shell C. These chambers are each formed of two metallic disks united at their outer edges, as shown by means of rivets. I have shown six of these chambers;- but I may use more or less, as desired. These chambers are connected in series, so that they will all contract and expand in unison and uniformly upon the application of linternal pressure. That one of the chambers, 'or D, which is nearest the chamber A2 hasits disk d united at its inner edge with the pipe or tube B3 by means of a hollow externally-serew-threaded coupling-piece D. The other disk, or d', of the chamber D andthe disk d2 of the chamber D2 are secured at their inner edges between nuts or rings d2 d4, having a screwthreaded connection, while the disk d5 of the chamber D2 and the disk d6 of the chamber D3 are united together by similar nuts or rings, and so on throughout the series. The valve-stem B2 passes centrally through the central openings in the nuts or rings d2 d4,

and an annular space is left between said.

valve-stein and the adjacent surfaces of the nuts or rings. Between adjacent pairs of nuts or rings are annular openings c, which afford free communication between the interior of the chambers D, &c., and the annular spaces between the nuts or rings and the valve-stem. It will'be quite apparent that pressure introduced through said annular space will cause an expansion of the chambers D, dac., and it will be equally apparent that such expansion will cause the valve B to be held iirmly seated.

Steam and water under pressure 'are admitted through an inlet E. The pressure will cause steam and water to 'be forced downwardly through the thin annular space between the pluglike portion B4 of the valvestem and the pipe or tube B3. This pressure will, when sufficient water has accumulated in the expansion-chambers D, doc., and in the pipe or tube'B, be sufficient to force water IOO through the openings c and into the interior of the valvestem B2, and thence upwardly through the restricted annular opening or passage between the iloat-spindle A5 and the interior of the valve-stem into the chamber A2, and will also force water upwardly through the hollow float-spindle and out at the upper end thereof above the float. The pressure has, however, been throttled by the openings c and the restricted opening or passage between the spindle and the valve-siem, and has accordingly been reduced.

Vhen water has accumulated in the chamber A2 to a sufficient height, it will raise the float Al. As soon as the iioat has been raised to such a 1 height that the float-spindle is moved past the openings e the pressure within the expansion-chambers, together with much of the condensed water, will pass through the hollow float-spindle and the expansion-chambers will suddenly collapse, thus raising the valve B from its seat and permitting a free outlet of pressure from the chamber A3 into the chamber A2, which will blow out all the water contained in the chamber A2 through the blow-olif pipe G.

Sediment which may collect in the lower part of the chamber A3 may be drawn off through a plug-hole l'fl.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, with a ease or shell divided internally into two chambers, one of which is provided with a blow-off and into the other of which steam and waters of condensation are introduced, of a float in the first-named chamber, a comnuinieation between said chambers, a Valve partially clos ing said comm unication, expansion-chambers connected with the valve and communicating with the second-named chamber for closing the valve, and a normally-restricted passage between. the chambers for waters of condensation and Athrough which the Water will ,be forced by steam-pressure, substantially as described, whereby when the water in the floatchamber causes the rising of the float to a sufficient height said opening will be enlarged to reduce the pressure in and cause the collapsing of the expansion-chambers and opening of said valve to blow out the water, substantially as described.

2. The combination of a case or shell divided internally into two chambers, one of which is provided with a blow-oil and into the other of which steam and waters oi' eon densation are introduced, a float in the firstnamed chamber, a communication between said chambers, a valve normally closing said communication, a tubular valve-stem, one or more expansion-ehambers connected to said valve-stein and communicating with the second-named chamber, a hollow spindle on said float, extending into said tubular Valvestem and with an opening into the Heat-chamber, and a normally-restricted opening admitting water and pressure through and around said hollow spindle, substantially as and for the purpose specified.
